Common issues with your constant pressure water pump Grundfos JP PM

Many domestic water pumps show the same failure problems towards the end of their service life. Grundfos pump failures are not the exception but the rule. The Grundfos Basicline JP Series Household pumps are susceptible to the power fluctuations typical in New Zealand. Power surges and voltage spikes can damage the water pump and cause Grundfos pump problems. The reasons are manifold: capacitors can burn out, and heads can war out. The jet booster pump can get hot if it is not vented correctly or runs out of water.

If your Grundfos pump is not working or you need some help with your Grundfos pump troubleshooting, call us at 0800 278 288. Our service team has many years of experience with Grundfos pump problems and is happy to help you. A water pump can get noisier over the years.
